Seven patients with Frykman type 7 and 8 distal radial fractures, who had been treated with external fixation, were noted to have significant over-distraction of 5-8 mm in the radio-carpal and mid-carpal joints. One patient, who also had abnormal negative ulnar variance of 2 mm, had a fair result using modified Gartland and Werly (1951) criteria. The remaining six patients had good results, indicating that over-distraction does not significantly alter the final outcome, so long as a normal distal radio-ulnar relationship is maintained.
7例接受外固定治疗的Frykman 7型和8型桡骨远端骨折患者，腕关节和腕中关节出现了5-8mm的明显过度牵引。1例患者尺骨负变异2mm，采用改良的Gartland和Werly（1951）标准评估，结果尚可。其余6例患者效果良好，表明只要维持正常的下尺桡关节关系，过度牵引不会显著改变最终结果。
